Answer:
0.56457
Step-by-step explanation:
log 3 with base 7 = (Log 3)/ (Log 7) = 0.47712125 / 0.845098040014
(Log 3) / (Log 7) = 0.56457
Answer: P = 0.75
Step-by-step explanation:
Hi!
The sample space of this problems is the set of all the possible sales. It is divided in the disjoint sets:
We have also the set of sales of boat accesories , the colored one in the image.
We are given the data:
From these relations you can compute the probabilities of the intersections colored in the image:
You are asked about the conditional probability:
To calculate this, you need . In the image you can see that the set is the union of the two disjoint pink and blue sets. Then:
Finally:
53-(64:8)+102=53-8+102=147
Two shapes.. a circle and a rectangle. The width of the rectangle serves as the diameter of the circle.
Length = 140 m ; Width = 68 m
Circumference of a circle = 2 π r
circumference of a cirlce = 2 * 3.14 * (68m/2) = 2 * 3.14 * 34 m = 213.52
length = 2 * 140 m = 280 m
perimeter of the oval = 213.52 m + 280 m = 493.52 m
